Continuous integration 在travis上的create react应用程序上运行夜视测试

我在travis上的create react应用程序服务器（

npm start

）上运行夜视测试时遇到问题。我正在用启动creat react应用程序

.travis.yml：

before_script:
  - npm --prefix ./client start ./client &
script: npm run test-ci

然而，当夜表运行时，我总是感到

Starting the development server...
Starting selenium server... Warning: The 'no-use-before-declare' rule requires type information.
ts-loader: Using typescript@2.5.3 and /home/travis/build/client/tsconfig.json

Note that the development build is not optimized.
To create a production build, use npm run build.
Error retrieving a new session from the selenium server

但是，在本地启动和运行nightwatch测试非常完美。

问题在于Chrome，而不是react或nightwatch的问题
